Input Delay
Two input delay settings, A and B, can be
selected and saved during system configu-
ration. These are provided for aligning the
audio input signals with latencies associ-
ated with video processing and display
systems. During normal operation of the
StudioComm system the active input de-
lay, A or B, can be selected. The channel
mute/solo button, stereo to mono button,
and 4-digit display are used to display and
select the input delay. When the mute/solo
button is pressed and held the LED associ-
ated with the stereo to mono button indi-
cates whether input delay A or input delay
B is active. The 4-digit display will show
the active delay time in milliseconds. While
pressing and holding the mute/solo button
the stereo to mono button can be pressed
to change the selected input delay. Refer
to Figure 11 for details. The selected input

Display and Display Mode
The Model 77’s 4-digit LED display shows
the post-fader surround and stereo digital
and analog monitor output levels as either
the amount of attenuation or the sound
pressure level (SPL). Both will indicate
level in dB. What the digits actually repre-
sent will depend upon how the Model 77
has been configured.
Display in dB of Attenuation
If configured for the attenuation mode
the display will show the post-fader moni-
tor output level as an attenuation value in
reference to the maximum output. This is
in the form of 0.5-dB steps less than the
maximum of 0.0 dB. So a display of –40.5
